Print on Demand. This book explores how a barred color in ostrich feathers is a genetic trait passed down from their parents, rather than a heterozygous condition resulting from the mixing of black and white feathers. The author begins with historical accounts of barred ostrich feather observations and unsuccessful attempts to breed this trait. The author then presents the results of their own experiments, which led to the discovery of a factor for barring that, when inherited from both parents, results in barred feathers. This discovery challenged the prevailing view that barring was a mosaic of black and white feathers, as it appeared in the first generation of offspring from black and white ostrich crosses. The author concludes that barring is a unit-character inherited separately from black and white pigmentation, providing new insights into the nature of inheritance and the complexity of genetic traits in ostriches. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book.

Riassunto

Excerpt from Studies on Inheritance in Poultry, Vol. 1: The Constitution of the White Leghorn Breed

The barred color-pattern is doubtless a. Very old and a by no means uncommon form of marking in the plumage of both wild and domestic birds. With some modification it is present in the feathering of many of our game birds, but it is in one or two varieties of domestic fowl that the character is to be seen in the purest and most extended form. At the present day the Barred Plymouth Rocks, an American breed, represent by far the most perfect development of the barred pattern to be found in any species or variety of bird.
